WEEK 6

1. KE and PE Calculations

2. Energy conservation calculations

Converting GPE to KE

Row 1: Complete GPE, no KE

GPE = m x g x h

GPE = 10 x 9.8 x 100

GPE = 9800 J

Row 2:

GPE = 10 x 9.8 x 90

GPE = 8820 J

Loss of PE, but...

KE = 1/2 x m x v2

KE = 1/2 x 10 x 142

KE = 980 J

GPE = KE = 8820 + 980 = 9800
